We bought the Sleep # Bed, the one that Lindsay Wagner does the commercials for, and have the 5000 which is their #1 seller, but I am not impressed ...the side of it have lost their shape, we've had it less than 1yr!!! everytime my husband gets in bed my side goes over the boxspring, and I am constantly pushing it back... I regret not going to test out the NASA material bed... the Tempurpedic one... Lots of luck...we are in the same boat...bed... etc...lol
P.s--i like it at 65 he likes it at 90!!
